Very poor timing to post this as it relates to the Springfield show in four months. I have number of OB discs with Dated Caps in a variety of glazes. Compare to the brown OB strings on either side. Full sunlight has washed out the colours somewhat. More discs available to pick and choose from, picture is only a sample. I am looking for nine dark gray discs to complete this summers project. Trade to take place at the Mid Ohio show in Nov. . I now have the 10 inch grey discs I need, but have more of these for trade for 3 smaller six inch discs, let me know what you have.
